摘要： A vehicular control apparatus that functions more reliably is provided. A quasi-abnormality control circuit brings one of a clock signal, an internal watchdog signal, and an answer signal into a quasi-abnormal state when an ignition is switched on. A clock determining circuit, an internal watchdog signal determining circuit, and a Q&A watchdog circuit output determination signals, respectively. One of the determination signals corresponds to a monitoring target signal brought into the quasi-abnormal state and indicates an abnormality. A reset signal determining circuit receives the determination signals, and generates a reset signal in accordance with determination results in the determination signals. A quasi-abnormality control circuit switches the monitoring target signal to be brought into the quasi-abnormal state each time the ignition is switched on.

摘要： There is provided an actuator control apparatus configured such that even when an electronic device that generates an electric signal to be used to control an actuator is provided in the form of a duplexed system, an increase in the number of communication paths between the electronic device and a controller is suppressed. A torque sensor and a rotation angle sensor are each provided in the form of a duplexed system. Two sets of a torque sensor and a rotation angle sensor are connected to a microcomputer via a SPI communication line. The torque sensors and the rotation angle sensors are connected to the microcomputer via CS communication lines, respectively. By selecting a communication target via a corresponding one of the CS communication lines, the microcomputer is able to receive multiple kinds of electric signals via each one of the SPI communication lines.

摘要： An ECU of a vehicle controls a motor on the vehicle. The ECU includes a microcomputer and a monitoring circuit. The monitoring circuit includes a rotation detection circuit that detects the number of rotations of the motor at a preset sampling interval, a control circuit including a logic circuit that controls an operation of the rotation detection circuit, and an inspection circuit that inspects of the control circuit. The microcomputer is started upon start of vehicle power supply and performs a specific process using the number of rotations of the motor detected by the rotation detection circuit. The inspection circuit performs the inspection of the control circuit in the monitoring circuit in a period in which the microcomputer is kept in a reset state after the vehicle power supply is turned on and which is within a sampling interval of the rotation detection circuit in the monitoring circuit.

摘要： A sensor apparatus includes an interface circuit to which one of a digital sensor and an analog sensor is connected as a sensor that generates an electric signal corresponding to a physical quantity of a detection target and a CPU that calculates the physical quantity of the detection target based on the electric signal generated by the sensor. The interface circuit has a first power supply circuit, a second power supply circuit, a receiver including a receiver circuit, and an operation determination circuit. The first power supply circuit generates an operating voltage of the sensor. The second power supply circuit generates a synchronizing signal for the digital signal. The receiver circuit receives an electric signal generated by the digital sensor. The operation determination circuit stops an operation at least of the second power supply circuit when the analog sensor is used.
